Grid-Tie Systems
Complete, Engineered, Packaged Solar Electric Systems
Finding ways to reduce costs and streamline operations is imperative in today’s increasingly competitive world of residential solar installation. Traditionally, residential solar electric systems involve design, documentation, sourcing of individual components, off-site receiving and staging, and one-of-a-kind on site installation. This method is complex, prone to error, and time consuming. SunWize Grid-Tie System packages are a superior approach, saving photovoltaic (PV) installers substantial time and money. Here’s how:
Complete, Packaged Kits: Delivered to the job site using a single part number
Everything needed is included. Time and effort is saved by not having to generate a bill of materials and order multiple items. A single part number gets the whole system shipped right to the customer’s driveway with no staging or double handling. Moreover, it eliminates the possibility of errors in ordering or in loading the truck. The job never comes to a halt because something is missing.
Engineered Systems: Proven reliability and permit-ready
SunWize Grid-Tie Systems are fully engineered and documented systems. They are proven, standard systems that free installers from having to design and engineer a system and generate drawings. Installers have everything they need to obtain a permit and facilitate an inspection. The resources usually expended in design, engineering and documentation can go right to the bottom line or be redirected to revenue generating activities.
Standard Systems: Increased installation efficiency
Grid-Tie Systems stay the same. Crews that continually work with Grid-Tie Systems quickly move through the learning curve and become very skilled and swift in their installation.
-
No Hidden Costs: Free delivery and no surcharges
-
Delivery is included and there are no handling charges.
-
Module and Balance of System Availability: No waiting
Many manufacturers are back-ordered and cannot ship until months after an order is placed. SunWize Grid-Tie Systems are in stock and ship one day after receipt of your order. Having modules and balance of system components available improves cash flow and increases customer satisfaction. The revenue from booked business is realized quicker. More importantly, the customer does not have to wait to start receiving the benefit of their PV system.
Broad Range of Systems: Choose from Over 300 configurations
Dealers select a given system size using a wide variety of module and inverter options. There is a configuration for virtually every residential customer situation.
SunWize Grid-Tie System Packages
SunWize Grid-Tie Systems contain high quality, UL listed components. Every component needed for a successful installation is included in the package. In addition to modules and inverters, each package includes SolarMount™ flush PV racks, and necessary hardware and electrical components. The installer supplies the wiring from the solar array to the main panel and lag bolts. Packages also include complete documentation, an installation guide and operation/owner’s manual.
Multiple systems can be installed for higher power output and systems may also be expanded in the future as budget or electrical requirements grow. Grid-Tie System packages can be installed on any type of composition or tile roof. The array is securely attached to the roof of the building with the mounts in compliance with US building codes.
Some SunWize Grid-Tie Systems are certified by the Florida Solar Energy Center (FSEC) for high quality, reliable and safe operation compliant to the NEC. The FSEC certificate is useful for permitting and the field inspections of installed systems.
